ABSTRACT:
A glass sheet bending apparatus (10) for bending glass sheets about a thermally stable reference is disclosed as including a mold shuttle (20) having a receptical member (22) providing a thermally stable reference point or center with respect to a glass sheet heating furnace (14) and an upper mold support including pin (62) cooperable with the first receptical member (22) so that a glass sheet can be accurately bent between molds (34, 32) mounted on the mold shuttle (20) and upper mold support (26) respectively. An upper mold support actuator (40) includes a second registering member (42) engaging a first registering member (28) of the upper mold support (26) for raising and lowering the upper mold support (26) and disengaging the upper mold support to allow relative movement between the actuator (40) and upper mold support (26) so that the same thereby realign and engage in a newly established registration during subsequent lifting of the upper mold support (26).
